AUTOMATIC GAS IGNITlNG DEVICE.

SPECIFICATION forming part of Letters Patent No. 689,102, dated December1'7, 1901.

Application filed August 30, 1900. Serial No. 28,556. (No model.)

To all whom, it may concern:

Be it known that I, ADOLF MARTINI, chemist, a citizen of the Kingdom ofPrussia, and a resident of Berlin, Germany, (whose postoffice address isLeipzigerstrasse 111,) have invented certain new and useful Improvementsin Automatic Gas-Igniting Devices, of which the following is aspecification.

The object of the presentinvention is an igniting device for suchgas-burners which have no chimney or similar device from which the jetof gas sallying forth from the orifice of the burner takes a certainply. The form of the igniter generally in use for burners provided withchimneys cannot be utilized for that purpose, for the pill ought to bebrought next to the orifice from which the gas is delivered in order tobring the jet of gas to impinge on it. The movable cover would be,consequently, also arranged next to the orifice and the flame and isthen exposed to a very intense heat, which deteriorates and spoils it ina short time. The gathering of soot on the cover could not be avoided ina device of this description. If, on the other hand, the cover werearranged so much to one side or the other of the orifice as to be notdirectly striken by the flame, it would not be moved by the dynamicforce of the gases, these escaping in a straight line upward withoutstriking the cover. The pill would therefore remain in the flame. Thecover could also be arranged such a distance above the flame that itwould not be deteriorated or that no deposits of soot would form on it 5but in this case the jet of gas would not strike the pill withsufficient pressure, and therefore would not cause its glowing.

The present invention unites all the features of the known igniter, butarranged in such a way as to obviate all the difficulties cited above.The cover is arranged at a considerable distance above the burner, sothat it, cannot be destroyed by the heat of the flame and that no sootcan be deposited -on it, whereas the pill has its place immediatelyabove the orifice of the burner Cover and pill are connected in such away that the latter is removed from the flame whenever the cover isremoved by the dynamic force of the gas-jet.

In order to adapt the apparatus to differ ent conditions-for example,varying pressures of gas, &c.'all parts of it are adjust= able.

The accompanying drawings show the apparatus in two differentpositions-n;amely, Figure 1 at rest, and Fig. 2 after the ignition ofthe flame has taken place and the cover has been removed from over theflame. Fig. 3 shows the cover seen from above.

To the burner a is fixed a horizontal arm I), which at its end bears avertical bracket 0, the height of which may be adjusted by suitablemeans. To the end of said bracket, which is preferably forked, is hingeda cover 6, consisting of a plate of mica. Said cover is nearlycounterbalanced by adjustable coun terpoises f. If left to itself, ittakes the horizontal position; but the current of hot air ascending fromthe flame suffices to-bring the cover into the position shown in Fig. 2and hold it therein. In order to offer more resistance to the ascendingcurrent, the free end 9 of the cover is bent downward in an obtuseangle.

As is already told, the ignition-pill it cannot be immediately fixed tothe cover, but must be brought nearer to the orifice of the burner. Itis therefore suspended from the cover by means of a thin wire 11, tiedto a bracket is on the cover'and extending through a longitudinal slot Zin the same. By means of this arrangement the pill is completely removedfrom the proximity of the flame whenever the cover is raised, Fig. 2.

The same result as with the hereinbeforedescribed device would beobtained by employing a cover without a slot, arranging the bracket withthe wire and the pill on the side of the former or in any other way.

What I claim is- 1. An ignition device for chimneyless gasburners,comprising a plate of non-combustible material arranged above theorifice of the burner and bearing on its upper side a bracket, havingsuspended therefrom by means of a wire an ignition-pill, whichordinarily hangs just over the orifice of said burner 3 an adjustablebracket fixed to said burner; said plate pivoting on a horizontal axisjournaled to said bracket; substantially as hereinbefore described.
